MACHINE FOR TRIMMING PLUME-STEMS.

Specification of Letters Patent.

Patented July 16, 1912.

Application filed September 8, 1911. Serial No. 648,366.

To all whom it may concern:

Be it known that I, EUGENE W. Moon, a

citizen of the United States, residing at New York city, county and State of New York, have invented a new and Improved Machine for Trimming Plume-Stems, of which the following is a specification.

This invention relates to a machine of novel construction for trimming or flattening simultaneously both sides of an ostrich or other plume stem in a rapid and accurate manner. Plumes with their stems thus reduced in thickness are used in the manufacture of compound plumes that are formed by superposing a selected number of the trimmed plumes and uniting their stems in suitable manner.

In the accompanying drawing: Figure 1 is a front elevation partly broken away of a machine embodying my invention; Fig. 2 a plan of the machine; Fig. 3 a side elevation partly in section thereof, and Fig. at a perspective view of a trimmed plume.

Upon a bed plate are mounted a pair of standards 11 in which is journaled the shaft 12 of a lower emery grinding wheel 13. One of the standards 11 is extended upwardly as at 14 and carries a fixed shaft 15 arranged in parallelism with shaft 12 and on which are free to turn the arms of an oscillative frame 16. In this frame is journaled the shaft 17 of an upper grinding wheel 18 the rim of which is located vertically above the rim of wheel 13. Wheel 18 is normally spaced from wheel 13 by a spiral spring 19 adapted to bear with its upper end against frame 16. Spring 19 encompasses a threaded pin 20 carrying a nut 21 by means of which the tension of the spring may be regulated.

Wheels 13, 18 are simultaneously rotated in opposite directions as indicated by the arrows 22 in Fig. 3. The means shown for driving the wheels consist of a power shaft 23 journaled in bearings 24 that depend from bed plate 10. Shaft 23 carries a pulley 25 which is operatively connected by belt 26 and pulley 27 to shaft 12 of wheel 13. A second crossed belt 28 running over pulley 25 and an idler 29 of shaft 15 rotates shaft 17 by means of pulley 30. Crossed belt 28 also runs over a tension roller 31 journaled in bearing 32 that turns on shaft 15, said tension roller being interposed between idler 29 and pulley 30.

, To the forward end of frame 16 are secured at 33 the two flanged cheeks of a curved guard 34 that straddles wheel 18. To frame 16 is further secured a handle 35, upon depressing which, said frame is swung down to correspondingly lower wheel 18 toward wheel 13 against the action of spring 19. Upon the release of the handle, the spring will automatically raise frame 16 to reestablish the necessary working space between the wheels. It is of course obvious that the action of handle 35 and spring 19 may be reversed, so that the spring is employed for depressing frame 16, while handle 35 is employed for raising the same.

A work table 36 slotted to accommodate wheel. 13 is adapted to receive the finished plumes. This table may be set at different elevations by slotted legs 37 and winged nuts 38 or in similar manner.

In use the plume 39, the stem of which is to be flattened is passed in the direction of the arrow 40 between the grinding wheels. While the plume is manually drawn forward, frame 16 is swung down by handle 35, so that wheel 18 is pressed firmly against the plume stem to in turn' press said stem firmly against the lower wheel 13. In this way both faces of the stem will be simultaneously ground off and flattened in the manner desired as shown at 4:1 in Fig. 4-, the finished plume being deposited on table 36. After the operation is completed, pressure on handle 35 is released to permit spring 19 to return frame 16 and wheel 18 to their normal position.

I claim:

1. A device of the character described, 3

comprising a standard, a lower grinding wheel journaled therein, an oscillative frame pivoted to the standard, an upper grinding wheel journaled in the frame in parallelism with the lower grinding wheel, and a spring engaging the oscillative frame and adapted to normally raise the upper grinding wheel a distance above the lower grinding wheel, thereby forming an intervening work-receiving space.

2-. A device of the character described, comprising a standard, a lower grinding wheel journaled therein, a spring influenced oscillating frame pivoted to the standard the axis of oscillation of said frame extending in parallelism with the grinding wheel axis, an upper grinding Wheel journaled in means for simultaneously rotating the the cgramme, inlparallelismbwith the lower grinding Wheels in opposite directions. grin ing whee a Work ta le having a slot 1 that accommodates the lower grinding EUGENE MOGH' 5 Wheel, a guard secured to the oscillating Witnesses:

frame and partly encompassing the upper FRANK v. BRIEsEN,- grinding Wheel, a handle on the guard, and KATHERYNE K0011.
